What is 42CrMo4 ultra-high strength steel？

42CrMo4 steel Description

42CrMo4 steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering and tempering, and good low temperature impact toughness.

42CrMo4 steel is suitable for large and medium-sized plastic molds that have certain requirements on strength and toughness.

Grade: 42CrMo4

Executive standard: EN 10083/3-2006

Features: high strength, good hardenability, good toughness

Advantages: good machinability, easy to polish, easy to bite

Type: Industrial Material

Function: locomotive traction gear, turbocharger transmission gear, rear axle, etc.

42CrMo4 steel is an industrial material.

It is used to manufacture forgings with higher strength and larger section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, rear axles, connecting rods and large-load spring clips.

42CrMo4 can also be used for drilling pipe joints and fishing tools for deep oil wells below 2000m.

Similar material: 42CrMo

42CrMo4 Features:

It has the characteristics of high strength, good hardenability, good toughness, small quenching deformation, high temperature creep strength and high durability strength.

42CrMo4 steel is an improvement of American AISI standard 4140 steel. The steel has good machinability, is easy to polish, easy to bite, and can be electroplated.

42CrMo4 alloy steel (rod, plate, square) is suitable for large and medium-sized plastic molds that have certain requirements on strength and toughness.
